Boyfriends🤦🏼‍♀️

Can anyone help me out a bit please?

So basically, my boyfriend and I are having an argument which is quite serious. He’s been off with be a couple of days and I’ve asked him “everything okay?” And he’ll say yes etc. But he’s been very blunt (considering he never is usually), and he keeps ignoring me (whereas he would start an argument with me if I did that). So anyway, we are arguing and I say “do you want to end things” because this has been going on for a while. And he does “I’m unsure, I don’t know”

So am I being psycho or was that a bad answer? Because now I’m getting doubts. We’ve been together for about 15 months tomorrow, and I’m 16. So please help me out
